I’m baffled by the so-called “conventional wisdom” that religious belief in America is on the decline. Quite the opposite is true. According to new Harvard research, only those with moderate religious ties are diminishing in number, but those who hold serious religious beliefs are rock steady in their faith. Americans are among the most religious people in the world — I myself am a devout Catholic — and in an era marked by economic and communal struggle, churches are thriving as sources of hope, support and guidance. To quote the Gospel of Saint Matthew, it’s from these small “mustard seeds” that we can grow and strengthen our families and communities.
